Front Coil Springs for MKIII Interceptors. There are two spring lengths for the Interceptor.  The MKIIIs had these slightly longer springs to raise up the headlights in the front (to meet U.S. regulations).  These are the stock ones, but if you want your car to be level (not higher in the front) order two of C5/64/C, for the MKII.   Compressing the springs is on the top of our list for unnerving Interceptor jobs! Careful, careful, carefully---
